摘要:
Described are on-die termination (ODT) systems and methods that facilitate high-speed communication between a transmitter die and a receiver die interconnected via one or more signal transmission lines. An ODT control system in accordance with one embodiment calibrates and maintains the termination resistances for the signal transmission lines. The ODT control system derives a number of calibration currents from precision voltage and resistance references and distributes the reference currents to a number of transmitters. Each transmitter then derives an ODT calibration signal using the respective reference current and another precision resistor, and then employs the calibration signal to calibrate local termination elements. Distributing calibrated currents provides excellent noise immunity, while limiting the requisite number of external voltage references reduces cost.

The present disclosure relates to a monitor for sensing and transmitting sounds in a baby's vicinity. The monitor includes a housing having a base and two substantially spaced-apart legs, the housing enclosing acoustical and electrical means for sensing and transmitting the sounds. The monitor is mountable on a support by straddling the support with the substantially spaced-apart legs. The present disclosure also relates to a sound monitoring system. The system includes the monitor, a receiver, and a charger. Further, the present disclosure relates to a method of securedly and releasably mounting the monitor to a support.

A latch for a cabinet door or drawer for preventing access to the interior of the cabinet or drawer. The latch includes a hook spring biased to engage a catch and that allows the door or drawer to be only slightly opened enough to allow a caregiver to reach the latch and displace it out of the way so that the door or drawer can then be fully opened. When released the latch returns to the biased position. The latch may also disengage the spring so as to be fully disabled and allow the door or drawer to be opened freely.

A lockable electrical outlet socket closure plug includes a plug housing including an inner plate and a socket blade appended to the inner plate and adapted to extend into a blade receiver opening formed in the electrical outlet socket. The closure plug further includes a retainer for selectively retaining the plug housing in a mounted position on an electrical outlet socket and a controller mounted for movement in the plug housing and arranged normally to reinforce the retainer to cause the plug housing to remain in the mounted position on the electrical outlet socket.

An infant thermometer assembly includes a cover portion and a thermometer portion pivotably coupled to the cover portion and pivotably movable relative to the cover portion about a pivot axis between a use position and a stowed position. The thermometer portion includes a probe and a housing coupled to the probe. The housing includes a display screen and a power button. The cover portion includes a cavity formed to receive at least a portion of the housing of the thermometer portion in the use and stowed positions and a cut-out formed to receive the probe of the thermometer portion in the stowed position.

A security gate for closing a passage has a pair of panels movable translationally with respect to one another to alter the effective width of the gate. An actuating mechanism for forcing the opposite ends of the panels against the sides of the passage includes a handle mounted on one of the panels controlling a latching device operative for locking the handle in a fixed relationship with respect to the other of the panels. The latching device in accordance with one embodiment includes a rack and brake. When the latch is engaged, a cam also controlled by the handle engages the panel on which the handle is mounted to force the two panels translationally further apart so as to bear firmly against the sides of the passage to hold the gate in position.
